THERMATEL ® TG1/TG2<br />
Thermal dispersion switch<br />
THERMAL DISPERSION<br />
DESCRIPTION<br />
Thermatel ® TG1/TG2 switches consist of electronics in a DIN rail housing and a remote<br />
sensor with aluminium or stainless steel sensor housing (max 500 m (1640 ft) away from<br />
electronics).<br />
TG1/TG2 switches can easily be adjusted to detect flow (gases and liquids), level or liquidliquid<br />
interface. Both units are 2-wire 24 V DC powered and intrinsically safe approved.<br />
The TG1 offers standard LED flow indication, the TG2 offers LED flow indication per<br />
NAMUR NE 44.<br />
FEATURES<br />
Temperature compensation<br />
Easy field calibration – pre-calibration from factory on request.<br />
Variable flow or flow / no flow detection of gases and liquids.<br />
Excellent low flow sensitivity.<br />
Automatic temperature compensation for repeatable alarm under varying process temperatures.<br />
Continuous diagnostics detect sensor fault.<br />
Continuous monitoring of flow rate versus setpoint via LED.<br />
mA output provides repeatable indication of flow rate and fault detection.<br />
Optional retractable fitting for dismantling under process conditions.<br />
Process conditions up to +450 °C (+850 °F) and 413 bar (6000 psi).<br />
Suited for SIL1 and SIL2 loops (full FMEDA report available).<br />
APPLICATIONS<br />
MEDIA: All types of gases and liquids.<br />
VESSELS: Pipe sizes down to 1 /4". Max sensor length up to 3,3 m. Can be installed at any<br />
angle vertically/horizontally.<br />
CONDITIONS: Can be used on conductive and non conductive media, very light density<br />
to heavy viscous media (up to 10.000 cP). Can be set to ignore foam, aeration, turbulence,<br />
and cavitation.<br />
